IF NOT EXIST

[Igor Korot <ikorot01@xxxxxxxxx>]

Hi, ALL,
I have a following statement:

IF NOT EXIST( SELECT 1 SELECT 1 FROM pg_proc AS proc, pg_namespace AS
ns ) CREATE FUNCTION();

Unfortunately trying to execute it thru the ODBC interface with:

ret = SQLExecDirect( m_hstmt, query, SQL_NTS );

gives syntax error near IF.

What is the proper way to do that?

Thank you.
